Master the Units!

Unit Master! is a learning app designed to help elementary school students (grades 4-6) understand unit conversions through fun and repetitive practice. You can review units such as length, weight, volume, area, and time through learning mode, conversion practice, quizzes, time trials, and review. Main Features * Learning mode allows you to learn while viewing unit relationships * Conversion practice allows you to input and check your answers * Quizzes offer both multiple-choice and input-based questions * Time trials require you to complete questions within a time limit * Review based on incorrect answers * Performance display including total number of questions answered, correct answer rate, and consecutive learning days * Coins and badges to motivate continued learning * BGM, sound effects, and furigana display settings For area units, you'll learn about the concept of multiplying by 100 with each step change. Word problems involving time and area are also provided, allowing you to practice matching units to different situations, rather than simply memorizing them.
